The GRACO HE120-0481 is an electric diaphragm pump designed for industrial fluid transfer applications. It features a 316L stainless steel fluid section, Buna-N diaphragm, and is intended for use in demanding environments where reliable, high-volume fluid handling is required. This pump is engineered to replace air-operated pumps with efficient electric technology, offering improved performance and ease of use within GRACO equipment.

Key Features:

• Electric Diaphragm Pump
• h120 Series, 3 in Fluid Inlet (Note: HE120-0481 is not directly listed, but HE120-0681 is a close variant with 3 in inlet; confirm exact size for HE120-0481)
• 316L Stainless Steel (fluid section, ball, seat), Buna-N (diaphragm), FEP Coated Aluminum (center section), EPDM (manifold O-ring)
• Designed for integration with GRACO fluid handling systems; compatible with Tri-Clamp connections
• Electric drive for efficient, reliable operation
• Stalls under pressure for safety
• AutoPrime feature for easy startup
• Compact and efficient design
• Easy maintenance with accessible components

Applications:
Industrial fluid transfer, including chemicals, water, and other compatible liquids. Suitable for mining, agriculture, and manufacturing environments where robust, high-capacity pumps are required.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise system integrity and void warranties.
• Ensure proper alignment of Tri-Clamp connections for leak-free operation
• Verify electrical supply matches pump requirements (typically 240 VAC, three-phase for similar models)
• Follow GRACO’s recommended maintenance schedule for diaphragm and ball checks
• Inspect O-rings and seals regularly for wear and replace as needed
• Consult the equipment manual for specific installation instructions
• Use appropriate personal protective equipment during installation and maintenance
• Test pump operation before full system integration
